Dataverse photo not always saving/downloading in full size (Canvas App)

Hi all,

I have seen a lot of posts about Dataverse images, but so far none that have solved my mystery (bug?). I have a canvas app which saves a photo to an image column in a Dataverse table. The user is able to launch the image to see it in full size in the browser. What I am seeing is that sometimes the image opens in full size and sometimes only in 144x144 (I know this is the size Dataverse saves images by default).

Here are a few examples of strange cases :

1) Earlier in the week I uploaded an image to the app, 2 users saw the image in full size (the tab on the browser even said 3024 x 4032) and one user saw the image in 144x144. Today when we use the same link which is labelled "download.aspx (3024x4032) (dynamics.com)" from a few days ago, everyone sees the image in 144x144.

2) Two images uploaded yesterday in the same way using the phone camera, one opens in full size, one opens in 144x144.

Here are some of the things I have checked :

Image column setting "Store full size image" is set to true
Url contains "&Full=true"
All code in the app uses "full"
No difference between uploading an image on the computer or through the phone camera, both show unpredictable results
No difference between being connected to wifi or using the phone network

Does anyone have any ideas as to what is going on and how to fix it ?

Thanks

Hi @HFG ,

Have you reviewed the following on displaying images?  https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/display-full-image-on-form

I know this is using the .Full property vs. the &full=true in the URI.

Overall this behavior is strange, just wondering if the above is an approach you have tried.

Hi @dpoggemann ,

Apologies for the slow reply and thanks for picking up on my post.

In my app I create a collection from the Dataverse table. The Image column in the collection is ThisRecord.zva_photomd.Full so I am using the full version of the photo as per the documentation. The image control then uses the column from this collection to display the image and the user clicks the image control to launch it in the browser.

Some more information regarding this issue...

Today the same photo which was launched in the same way through the app, one in Edge and one in Chrome, showed in different sizes - Edge large and Chrome small. This same image showed small for another user when using Edge. It also opens as small if I launch it from a Model Driven app with the "timestamp" in the url. If I remove the time stamp it opens as large. The image that opened as small through the app for the second user in Edge didn't include the timestamp in the url so unfortunately this is not the issue.

I am having a really hard time pinpointing what is going on. Help !

Hi @HFG, were you able to solve this issue? I am having the same issue. Sometimes images get uploaded as full images and sometimes as thumbnails. Thanks.

Hi @Yasir_rd ,

In my case I was pulling the image into a variable. I pull the Dataverse image column into the variable and then in the image control is varImage.Full. This variable was then passed back to the data source in the Patch "ProofOfPurchaseMD: {Full : varImage.Full; Value : varImage.Value}" and I believe this could be where the issue was. The small image seemed to only appear after the user modified a ticket. I didn't fully solve the problem, but the way I got around it was to only repatch the image if the user changes it. If I investigated it further, there may be a better way to pull the image into the variable, such as ImageColumn.Full rather than the whole column.
